RSS Reader - GreatNews

I've been using GreatNews [curiostudio.com] as a portable RSS Reader which I discovered through Wikipedia [wikipedia.org]. My work environment is Windows and my home network is mainly Linux plus one Windows machine. The portability is my first love, and I have a great appreciation for RSS readers [& feeds] for their efficiency of allowing me to keep up to date with news on a wide variety of topics.

I'm wondering what others think of GreatNews [curiostudio.com] or if there is any other portable standalone dedicated RSS readers others fancy? [that are not dependant on other applications ie. .net, java]

 

GreatNews is a fantastic piece of software
